Methods and Results

We performed 138 percutaneous balloon kyphoplasty procedures in 85 patients during august 2007 to march 2010. Gender distribution was 25 males and 60 females. Age distribution was 33 to 85 years, with an average age of 67.4 years.

The senior surgeon attempted vertebral biopsy during percutaneous balloon kyphoplasty procedure only when there was a clinical/operative suspicion of malignancy. We did not routinely biopsy all vertebrae, as this would mean additional procedure adding to the cost and operating time.

In 42 procedures vertebral biopsy was attempted, of which 5 samples were reported as insufficient specimen. 37 biopsies (88%) were successfully analyzed. 3 biopsies (8.1%) were positive for malignancy. There were no complications encountered in the cases where additional biopsy procedure was carried out.

Methods and Results

We performed 138 Balloon kyphoplasty procedures in 85 patients during august 2007 to march 2010. Data was collected and analyzed in all these cases. Gender distribution was 60 females and 25 males. Age distribution was 33 to 85 years, with an average age of 67.4 years. Indications of surgery were vertebral fractures due to osteoporosis in 81% of the procedures, trauma in 13% and malignancy in 6%. The most common vertebral levels of the kyphoplasty were at T12 in 32 procedures (23%) and L1 in 28 procedures (20%). Eggshell technique was introduced in 2009 where technical problems were encountered during cementing process.

All patients had reduced pain levels, which was assessed by visual analog score. The average length of hospital stay was 2.5 days. Complications were 9 (6.5%) cement leaks (all within one cm from the vertebral body) in procedures performed before the introduction of eggshell technique and no cement leak following the introduction of eggshell technique, 5 (3.6%) fresh fractures, 2 (1.4%) intra-operative fractures and 1 (0.73%) rupture of balloon. There were no complications of cord compression, motor deficit, infection, allergy to cement or pulmonary embolism noted. 30-day mortality rate was zero.
